Quick Answer
CoolSculpting uses controlled cold (cryolipolysis) to destroy fat cells. Emsculpt uses electromagnetic energy to trigger intense muscle contractions, and newer versions add radiofrequency for fat reduction. RedSculpt™ combines electromagnetic muscle stimulation, micro-current, and radiofrequency to reduce fat, tone muscle, and tighten skin in one session. Gentle Glo™ uses low-level green laser energy to shrink fat cells and reduce inches. The best choice depends on whether your goal is fat reduction, muscle tone, inch loss, or a combination.
I spent years marketing body sculpting devices for med spas before co-founding REDSOL. I've seen the sales pitches for nearly every machine on the market, and I've seen how confusing it gets for clients trying to compare them.
So here's an honest, side-by-side comparison of four popular approaches - including two we don't offer - so you can make the right decision for your body, wherever you end up getting treated.
The Four Technologies in Plain English
CoolSculpting (Cryolipolysis)
How it works: A cooling applicator chills fat to a temperature that damages fat cells while sparing the surrounding skin. Over the following weeks, the body clears the damaged cells.
Goal: Fat reduction.
What it feels like: Intense cold and suction at first, then numbness. Some people experience temporary soreness, numbness, or bruising afterward.
Worth knowing: CoolSculpting is clinically tested and well established. A rare side effect called paradoxical adipose hyperplasia - where the treated area grows firmer and larger instead of smaller - has been reported. Ask any provider about it.
Emsculpt (Electromagnetic Muscle Stimulation)
How it works: High-intensity focused electromagnetic energy causes powerful muscle contractions. Newer versions add radiofrequency heating to target fat in the same session.
Goal: Muscle building and toning, plus fat reduction in versions with radiofrequency.
What it feels like: Strong, rhythmic muscle contractions - like an intense workout.
RedSculpt™ (Electromagnetic + Micro-Current + Radiofrequency)
How it works: RedSculpt combines high-intensity electromagnetic muscle stimulation, micro-current muscle activation, and micro-current radiofrequency in a single 30-minute session.
Goal: Fat reduction, muscle toning, and skin tightening at the same time.
What it feels like: Strong muscle contractions, completely painless. No downtime.
Treatment areas: Abdomen, buttocks, thighs, and arms.

Gentle Glo™ (Low-Level Laser)
How it works: A 532nm green laser creates temporary pores in fat cell membranes. Stored fat is released and flushed out through the lymphatic system. Fat cells shrink but are not destroyed.
Goal: Fat cell shrinkage and inch reduction.
What it feels like: Gentle warmth. No pain, no cold, no contractions. No downtime.
Treatment areas: Abdomen, flanks, back, buttocks, thighs, knees, arms, neck, jawline, chest, calves, and hips.

Side-by-Side Comparison
| CoolSculpting | Emsculpt | RedSculpt™ | Gentle Glo™ | |
|---|---|---|---|---|
| Technology | Controlled cooling | Electromagnetic (+ RF in newer versions) | Electromagnetic + micro-current + RF | Low-level green laser (532nm) |
| Primary goal | Fat reduction | Muscle tone (+ fat with RF) | Fat reduction, muscle tone, skin tightening | Inch loss, fat cell shrinkage |
| Builds muscle | No | Yes | Yes | No |
| Effect on fat cells | Destroys them | Reduces fat (RF versions) | Reduces fat | Shrinks them (cells stay intact) |
| Sensation | Cold, suction, numbness | Strong contractions | Strong contractions, painless | Gentle warmth |
| Downtime | Possible temporary soreness/numbness | None | None | None |
| Available at REDSOL | No | No | Yes | Yes |
Which Option Fits Your Goal?
"I want a firmer, more defined stomach, glutes, or arms." Look at muscle-building technologies: RedSculpt or Emsculpt. Freezing and laser treatments don't build muscle.
"I just want to lose inches around my waist and back." Gentle Glo is designed for exactly that, and it treats areas like the flanks and back that many devices can't reach.
"I want fat reduction and tighter skin, not just muscle." RedSculpt's radiofrequency component adds skin tightening alongside fat reduction and muscle tone.
"I hate the idea of cold or suction." RedSculpt and Gentle Glo involve neither.
"I want to treat my chin, knees, or bra-line area." Gentle Glo covers these areas. RedSculpt does not.
Why We Chose RedSculpt and Gentle Glo for REDSOL
When Joshua and I built REDSOL, we wanted two technologies that covered different goals without overlapping. RedSculpt handles muscle, fat, and skin on the body's major areas. Gentle Glo handles inch loss across nearly every other area, with no sensation beyond warmth.
Between the two, we can build a plan for almost any body sculpting goal, and combine them when it makes sense. And because neither involves freezing, neither carries the risks associated with cold-based treatments.
Questions to Ask Any Body Sculpting Provider
- What technology do you use, and how exactly does it work?
- Why is it the right choice for my specific goal?
- How many sessions will I need?
- What are the possible side effects?
- How will you track my results?
A good provider answers all of these without hesitation.
